FIELD OF INVENTION

This invention relates generally to the field of soybean breeding,specifically relating to a soybean variety designated XBP49006.

BACKGROUND

The present invention relates to a new and distinctive soybean varietydesignated XBP49006, which has been the result of years of carefulbreeding and selection in a comprehensive soybean breeding program.There are numerous steps in the development of any novel, desirablesoybean variety. Plant breeding begins with the analysis and definitionof problems and weaknesses of the current germplasm, the establishmentof program goals, and the definition of specific breeding objectives.The next step is selection of germplasm that possess the traits to meetthe program goals. The breeder's goal is to combine in a single varietyan improved combination of desirable traits from the parental germplasm.These important traits may include but are not limited to: higher seedyield, resistance to diseases and insects, tolerance to drought andheat, altered fatty acid profile, abiotic stress tolerance, improvementsin compositional traits and better agronomic characteristics.

These product development processes, which lead to the final step ofmarketing and distribution, can take from six to twelve years from thetime the first cross is made until the finished seed is delivered to thefarmer for planting. Therefore, development of new varieties is atime-consuming process that requires precise planning, efficient use ofresources, and a minimum of changes in direction.

Soybean (Glycine max), is an important and valuable field crop. Thus, acontinuing goal of soybean breeders is to develop stable, high yieldingsoybean varieties that are agronomically sound. The reasons for thisgoal are to maximize the amount of grain produced on the land used andto supply food for both animals and humans. To accomplish this goal, thesoybean breeder must select and develop soybean plants that have thetraits that result in superior varieties.

The soybean is the world's leading source of vegetable oil and proteinmeal. The oil extracted from soybeans is used for cooking oil,margarine, and salad dressings. Soybean oil is composed of saturated,monounsaturated and polyunsaturated fatty acids. It has a typicalcomposition of 11% palmitic, 4% stearic, 25% oleic, 50% linoleic and 9%linolenic fatty acid content (“Economic Implications of Modified SoybeanTraits Summary Report”, Iowa Soybean Promotion Board & American SoybeanAssociation Special Report 92S, May 1990). Changes in fatty acidcomposition for improved oxidative stability and nutrition are alsoimportant traits. Industrial uses for processed soybean oil includeingredients for paints, plastics, fibers, detergents, cosmetics, andlubricants. Soybean oil may be split, inter-esterified, sulfurized,epoxidized, polymerized, ethoxylated, or cleaved. Designing andproducing soybean oil derivatives with improved functionality,oliochemistry, is a rapidly growing field. The typical mixture oftriglycerides is usually split and separated into pure fatty acids,which are then combined with petroleum-derived alcohols or acids,nitrogen, sulfonates, chlorine, or with fatty alcohols derived from fatsand oils.

Soybean is also used as a food source for both animals and humans.Soybean is widely used as a source of protein for animal feeds forpoultry, swine and cattle. During processing of whole soybeans, thefibrous hull is removed and the oil is extracted. The remaining soybeanmeal is a combination of carbohydrates and approximately 50% protein.

For human consumption soybean meal is made into soybean flour which isprocessed to protein concentrates used for meat extenders or specialtypet foods. Production of edible protein ingredients from soybean offersa healthy, less expensive replacement for animal protein in meats aswell as dairy-type products.

It has beenself-pollinated a sufficient number of generations, with carefulattention to uniformity of plant type to ensure a sufficient level ofhomozygosity and phenotypic stability. The variety has been increasedwith continued observation for uniformity. No variant traits have beenobserved or are expected.

A variety description of Soybean variety XBP49006 is provided inTable 1. Traits reported are average values for all locations and yearsor samples measured.

Soybean variety XBP49006, being substantially homozygous, can bereproduced by planting seeds of the variety, growing the resultingsoybean plants under self-pollinating or sib-pollinating conditions, andharvesting the resulting seed, using techniques familiar to theagricultural arts.

Performance Examples of XBP49006

As shown in Table 2, the traits and characteristics of soybean varietyXBP49006 are given in paired comparisons with other varieties. Traitsreported are mean values for all locations and years where pairedcomparison data was obtained.

Genetic Marker Profile

In addition to phenotypic observations, a plant can also be identifiedby its genotype. The genotype of a plant can be characterized through agenetic marker profile which can identify plants of the same variety ora related variety, or which can be used to determine or validate apedigree. Genetic marker profiles can be obtained by techniques such asrestriction fragment length polymorphisms (RFLPs), randomly amplifiedpolymorphic DNAs (RAPDs), arbitrarily primed polymerase chain reaction(AP-PCR), DNA amplification fingerprinting (DAF), sequence characterizedamplified regions (SCARs), amplified fragment length polymorphisms(AFLPs), simple sequence repeats (SSRs) also referred to asmicrosatellites, or single nucleotide polymorphisms (SNPs). For example,see Cregan et al, “An Integrated Genetic Linkage Map of the SoybeanGenome” Crop Science 39:1464-1490 (1999), and Berry et al., AssessingProbability of Ancestry Using Simple Sequence Repeat Profiles:Applications to Maize Inbred Lines and Soybean Varieties” Genetics165:331-342 (2003), each of which are incorporated by reference hereinin their entirety.

Particular markers used for these purposes are not limited to anyparticular set of markers, but are envisioned to include any type ofmarker and marker profile which provides a means of distinguishingvarieties. One method of comparison is to use only homozygous loci forXBP49006. For example, one set of publicly available markers which couldbe used to screen and identify variety XBP49006 is disclosed in Table 3.

Primers and PCR protocols for assaying these and other markers aredisclosed in Soybase (sponsored by the USDA Agricultural ResearchService and Iowa State University) located at the world wide web at129.186.26.94/SSR.html. In addition to being used for identification ofsoybean variety XBP49006 and plant parts and plant cells of varietyXBP49006, the genetic profile may be used to identify a soybean plantproduced through the use of XBP49006 or to verify a pedigree for progenyplants produced through the use of XBP49006. The genetic marker profileis also useful in breeding and developing backcross conversions.

The present invention comprises a soybean plant characterized bymolecular and physiological data obtained from the representative sampleof said variety deposited with the ATCC. Further provided is a soybeanplant formed by the combination of the disclosed soybean plant or plantcell with another soybean plant or cell and comprising the homozygousalleles of the variety.

Means of performing genetic marker profiles using SSR polymorphisms arewell known in the art. A marker system based on SSRs can be highlyinformative in linkage analysis relative to other marker systems in thatmultiple alleles may be present. Another advantage of this type ofmarker is that, through use of flanking primers, detection of SSRs canbe achieved, for example, by using the polymerase chain reaction (PCR),thereby eliminating the need for labor-intensive Southern hybridization.PCR detection is done using two oligonucleotide primers flanking thepolymorphic segment of repetitive DNA to amplify the SSR region.

Following amplification, markers can be scored by electrophoresis of theamplification products. Scoring of marker genotype is based on the sizeof the amplified fragment, which correlates to the number of base pairsof the fragment. While variation in the primer used or in laboratoryprocedures can affect the reported fragment size, relative values shouldremain constant regardless of the specific primer or laboratory used.When comparing varieties it is preferable if all SSR profiles areperformed in the same lab.

Primers used are publicly available and may be found in Soybase orCregan (1999 Crop Science 39:1464-1490). See also, WO 99/31964Nucleotide Polymorphisms in Soybean, U.S. Pat.

The SSR profile of soybean plant XBP49006 can be used to identify plantscomprising XBP49006 as a parent, since such plants will comprise thesame homozygous alleles as XBP49006. Because the soybean variety isessentially homozygous at all relevant loci, most loci should have onlyone type of allele present. In contrast, a genetic marker profile of anF1 progeny should be the sum of those parents, e.g., if one parent washomozygous for allele x at a particular locus, and the other parenthomozygous for allele y at that locus, then the F1 progeny will be xy(heterozygous) at that locus. Subsequent generations of progeny producedby selection and breeding are expected to be of genotype xx(homozygous), yy (homozygous), or xy (heterozygous) for that locusposition. When the F1 plant is selfed or sibbed for successive filialgenerations, the locus should be either x or y for that position.

In addition, plants and plant parts substantially benefiting from theuse of XBP49006 in their development, such as XBP49006 comprising abackcross conversion, transgene, or genetic sterility factor, may beidentified by having a molecular marker profile with a high percentidentity to XBP49006. Such a percent identity might be 90%, 95%, 96%,97%, 98%, 99%, 99.5% or 99.9% identical to XBP49006.

The SSR profile of XBP49006 also can be used to identify essentiallyderived varieties and other progeny varieties developed from the use ofXBP49006, as well as cells and other plant parts thereof. Such plantsmay be developed using the markers identified in WO 00/31964, U.S. Pat.No. 6,162,967 and U.S. Pat. No. 7,288,386. Progeny plants and plantparts produced using XBP49006 may be identified by having a molecularmarker profile of at least 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%,70%, 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%,88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or 99.5%genetic contribution from soybean variety, as measured by either percentidentity or percent similarity. Such progeny may be furthercharacterized as being within a pedigree distance of XBP49006, such aswithin 1, 2, 3, 4 or 5 or less cross-pollinations to a soybean plantother than XBP49006, or a plant that has XBP49006 as a progenitor.Unique molecular profiles may be identified with other molecular toolssuch as SNPs and RFLPs.

Introduction of a New Trait or Locus into XBP49006

Variety XBP49006 represents a new base genetic variety into which a newlocus or trait may be introgressed. Direct transformation andbackcrossing represent two important methods that can be used toaccomplish such an introgression.

A backcross conversion of XBP49006 occurs when DNA sequences areintroduced through backcrossing (Hallauer et al. in Corn and CornImprovement, Sprague and Dudley, Third Ed. 1998), with XBP49006 utilizedas the recurrent parent. Both naturally occurring and transgenic DNAsequences may be introduced through backcrossing techniques. A backcrossconversion may produce a plant with a trait or locus conversion in atleast two or more backcrosses, including at least 2 backcrosses, atleast 3 backcrosses, at least 4 backcrosses, at least 5 backcrosses, ormore. Molecular marker assisted breeding or selection may be utilized toreduce the number of backcrosses necessary to achieve the backcrossconversion. For example, see Openshaw, S. J. et al., Marker-assistedSelection in Backcross Breeding. In: Proceedings Symposium of theAnalysis of Molecular Data, August 1994, Crop Science Society ofAmerica, Corvallis, Oreg., where it is demonstrated that a backcrossconversion can be made in as few as two backcrosses.

The complexity of the backcross conversion method depends on the type oftrait being transferred (a single gene or closely linked genes comparedto unlinked genes), the level of expression of the trait, the type ofinheritance (cytoplasmic or nuclear), dominant or recessive traitexpression, and the types of parents included in the cross. It isunderstood by those of ordinary skill in the art that for single genetraits that are relatively easy to classify, the backcross method iseffective and relatively easy to manage. (See Hallauer et al. in Cornand Corn Improvement, Sprague and Dudley, Third Ed. 1998). Desiredtraits that may be transferred through backcross conversion include, butare not limited to, sterility (nuclear and cytoplasmic), fertilityrestoration, nutritional enhancements, drought tolerance, nitrogenutilization, altered fatty acid profile, low phytate, industrialenhancements, disease resistance (bacterial, fungal or viral), insectresistance, and herbicide resistance. In addition, a recombination siteitself, such as an FRT site, Lox site or other site specific integrationsite, may be inserted by backcrossing and utilized for direct insertionof one or more genes of interest into a specific plant variety. A singlelocus may contain several transgenes, such as a transgene for diseaseresistance that also contains a transgene for herbicide resistance. Thegene for herbicide resistance may be used as a selectable marker and/oras a phenotypic trait. A single locus conversion of site specificintegration system allows for the integration of multiple genes at aknown recombination site in the genome.

The backcross conversion may result from either the transfer of adominant allele or a recessive allele. Selection of progeny containingthe trait of interest is accomplished by direct selection for a traitassociated with a dominant allele. Transgenes transferred viabackcrossing typically function as a dominant single gene trait and arerelatively easy to classify. Selection of progeny for a trait that istransferred via a recessive allele requires growing and selfing thefirst backcross generation to determine which plants carry the recessivealleles. Recessive traits may require additional progeny testing insuccessive backcross generations to determine the presence of the locusof interest. The last backcross generation is usually selfed to givepure breeding progeny for the trait(s) being transferred, although abackcross conversion with a stably introgressed trait may also bemaintained by further backcrossing to the recurrent parent withsubsequent selection for the trait.

Along with selection for the trait of interest, progeny are selected forthe phenotype of the recurrent parent. The backcross is a form ofinbreeding, and the features of the recurrent parent are automaticallyrecovered after successive backcrosses. Poehlman suggests from one tofour or more backcrosses, but as noted above, the number of backcrossesnecessary can be reduced with the use of molecular markers (Poehlman etal (1995) Breeding Field Crops, 4th Ed., Iowa State University Press,Ames, Iowa). Other factors, such as a genetically similar donor parent,may also reduce the number of backcrosses necessary. As noted byPoehlman, backcrossing is easiest for simply inherited, dominant andeasily recognized traits.

One process for adding or modifying a trait or locus in soybean varietyXBP49006 comprises crossing XBP49006 plants grown from XBP49006 seedwith plants of another soybean plant that comprises a desired traitlacking in XBP49006, selecting F1 progeny plants that possess thedesired trait or locus to produce selected F1 progeny plants, crossingthe selected progeny plants back to XBP49006 plants to producebackcross) (BC1) progeny plants. The BC1F1 progeny plants that have thedesired trait and the morphological characteristics of soybean varietyXBP49006 are selected and backcrossed to XBP49006 to generate BC2F1progeny plants. Additional backcrossing and selection of progeny plantswith the desired trait will produce BC3F1, BC4F1, BC5F1, . . . BC×F1generations of plants. The backcross populations of XBP49006 may befurther characterized as having the physiological and morphologicalcharacteristics of soybean variety XBP49006 listed in Table 1 asdetermined at the 5% significance level when grown in the sameenvironmental conditions and/or may be characterized by percentsimilarity or identity to XBP49006 as determined by SSR or othermolecular markers. The above method may be utilized with fewerbackcrosses in appropriate situations, such as when the donor parent ishighly related or molecular markers are used in the selection step.Desired traits that may be used include those nucleic acids known in theart, some of which are listed herein, that will affect traits throughnucleic acid expression or inhibition. Desired loci also include theintrogression of FRT, Lox and/or other recombination sites for sitespecific integration. Desired loci further include QTLs, which may alsoaffect a desired trait.

In addition, the above process and other similar processes describedherein may be used to produce first generation progeny soybean seed byadding a step at the end of the process that comprises crossing XBP49006with the introgressed trait or locus with a different soybean plant andharvesting the resultant first generation progeny soybean seed.

Transgenes and transformation methods provide means to engineer thegenome of plants to contain and express foreign genetic elements,additional copies of endogenous elements, and/or modified versions ofnative or endogenous genetic elements in order to alter the traits of aplant in a specific manner that would be difficult or impossible toobtain with traditional plant breeding alone. Any heterologous DNAsequence(s), whether from a different species or from the same species,which are inserted into the genome using transformation, backcrossing orother methods known to one of skill in the art are referred to hereincollectively as transgenes. The sequences are heterologous based onsequence source, location of integration, operably linked elements, orany combination thereof. Transgenic variants of soybean varietyXBP49006, seeds, cells, and parts thereof or derived therefrom areprovided.

In one example a process for modifying soybean variety XBP49006 with theaddition of a desired trait, said process comprising transforming asoybean plant of variety XBP49006 with a transgene that confers adesired trait is provided. Therefore, transgenic XBP49006 soybean cells,plants, plant parts, and seeds produced from this process are provided.In some examples, the desired trait may be one or more of herbicideresistance, insect resistance, disease resistance, decreased phytate,modified fatty acid profile, modified fatty acid content, orcarbohydrate metabolism. The specific gene may be any known in the artor listed herein, including but not limited to a polynucleotideconferring resistance to imidazolinone, sulfonylurea, glyphosate,glufosinate, triazine or benzonitrile herbicides; a polynucleotideencoding a Bacillus thuringiensis polypeptide, a polynucleotide encodinga phytase, a fatty acid desaturase (e.g., FAD-2, FAD-3), galactinolsynthase, a raffinose synthetic enzyme; or a polynucleotide conferringresistance to soybean cyst nematode, brown stem rot, Phytophthora rootrot, soybean mosaic virus, sudden death syndrome, or other plantpathogen.

Numerous methods for plant transformation have been developed, includingbiological and physical plant transformation protocols. See, forexample, Miki et al., “Procedures for Introducing Foreign DNA intoPlants” in Methods in Plant Molecular Biology and Biotechnology, Glick,B. R. and Thompson, J. E. Eds. (CRC Press, Inc., Boca Raton, 1993) pages67-88; and Armstrong, “The First Decade of Maize Transformation: AReview and Future Perspective” (Maydica 44:101-109, 1999). In addition,expression vectors and in vitro culture methods for plant cell or tissuetransformation and regeneration of plants are available. See, forexample, Gruber et al., “Vectors for Plant Transformation” in Methods inPlant Molecular Biology and Biotechnology, Glick, B. R. and Thompson, J.E. Eds. (CRC Press, Inc., Boca Raton, 1993) pages 89-119.

The most prevalent types of plant transformation involve theconstruction of an expression vector. Such a vector comprises a DNAsequence that contains a gene under the control of or operatively linkedto a regulatory element, for example a promoter. The vector may containone or more genes and one or more regulatory elements.

A genetic trait which has been engineered into the genome of aparticular soybean plant may then be moved into the genome of anothervariety using traditional breeding techniques that are well known in theplant breeding arts. For example, a backcrossing approach is commonlyused to move a transgene from a transformed soybean variety into anelite soybean variety, and the resulting backcross conversion plantwould then contain the transgene(s).

Various genetic elements can be introduced into the plant genome usingtransformation. These elements include, but are not limited to genes;coding sequences; inducible, constitutive, and tissue specificpromoters; enhancing sequences; and signal and targeting sequences.

Transgenic plants can be used to produce commercial quantities of aforeign protein. Thus, techniques for the selection and propagation oftransformed plants, which are well understood in the art, yield aplurality of transgenic plants that are harvested in a conventionalmanner, and a foreign protein then can be extracted from a tissue ofinterest or from total biomass. Protein extraction from plant biomasscan be accomplished by known methods which are discussed, for example,by Heney and Orr, Anal. Biochem. 114:92-6 (1981).

A genetic map can be generated, primarily via conventional restrictionfragment length polymorphisms (RFLP), polymerase chain reaction (PCR)analysis, simple sequence repeats (SSR) and single nucleotidepolymorphisms (SNP) that identifies the approximate chromosomal locationof the integrated DNA molecule. For exemplary methodologies in thisregard, see Glick and Thompson, Methods in Plant Molecular Biology andBiotechnology, pp. 269-284 (CRC Press, Boca Raton, 1993).

Wang et al. discuss “Large Scale Identification, Mapping and Genotypingof Single-Nucleotide Polymorphisms in the Human Genome”, Science,280:1077-1082, 1998, and similar capabilities are becoming increasinglyavailable for the soybean genome. Map information concerning chromosomallocation is useful for proprietary protection of a subject transgenicplant. If unauthorized propagation is undertaken and crosses made withother germplasm, the map of the integration region can be compared tosimilar maps for suspect plants to determine if the latter have a commonparentage with the subject plant. Map comparisons could involvehybridizations, RFLP, PCR, SSR, sequencing or combinations thereof, allof which are conventional techniques. SNPs may also be used alone or incombination with other techniques.

Likewise, plants can be genetically engineered to express variousphenotypes of agronomic interest. Through the transformation of soybeanthe expression of genes can be altered to enhance disease resistance,insect resistance, herbicide resistance, agronomic, grain quality andother traits. Transformation can also be used to insert DNA sequenceswhich control or help control male-sterility. DNA sequences native tosoybean as well as non-native DNA sequences can be transformed intosoybean and used to alter levels of native or non-native proteins.Various promoters, targeting sequences, enhancing sequences, and otherDNA sequences can be inserted into the genome for the purpose ofaltering the expression of proteins. Reduction of the activity ofspecific genes (also known as gene silencing, or gene suppression) isdesirable for several aspects of genetic engineering in plants.

Many techniques for gene silencing are well known to one of skill in theart, including but not limited to knock-outs (such as by insertion of atransposable element such as mu (Vicki Chandler, The Maize Handbook ch.118 (Springer-Verlag 1994) antisense technology (see, e.g., Sheehy etal.

Exemplary nucleotide sequences that may be altered by geneticengineering include, but are not limited to, those categorized below.

1. Transgenes that Confer Resistance to Insects or Disease and thatEncode:

(A) Plant disease resistance genes. Plant defenses are often activatedby specific interaction between the product of a disease resistance gene(R) in the plant and the product of a corresponding avirulence (Avr)gene in the pathogen. A plant variety can be transformed with clonedresistance gene to engineer plants that are resistant to specificpathogen strains. See, for example Jones et al., Science 266: 789 (1994)(cloning of the tomato Cf-9 gene for resistance to Cladosporium fulvum);Martin et al., Science 262:1432 (1993) (tomato Pto gene for resistanceto Pseudomonas syringae pv. tomato encodes a protein kinase); Mindrinoset al., Cell 78:1089 (1994) (Arabidopsis RPS2 gene for resistance toPseudomonas syringae), McDowell & Woffenden, (2003) Trends Biotechnol.21:178-83 and Toyoda et al., (2002) Transgenic Res. 11:567-82. A plantresistant to a disease is one that is more resistant to a pathogen ascompared to the wild type plant.

(B) A Bacillus thuringiensis (Bt) protein, a derivative thereof or asynthetic polypeptide modeled thereon. See, for example, Geiser et al.,Gene 48:109 (1986), who disclose the cloning and nucleotide sequence ofa Bt delta-endotoxin gene. Moreover, DNA molecules encodingdelta-endotoxin genes can be purchased from American Type CultureCollection (Rockville, Md.), for example, under ATCC Accession Nos.40098, 67136, 31995 and 31998.

4. Genes that Control Male-Sterility

There are several methods of conferring genetic male sterilityavailable, such as multiple mutant genes at separate locations withinthe genome that confer male sterility, as disclosed in U.S. Pat. Nos.4,654,465 and 4,727,219 to Brar et al. and chromosomal translocations asdescribed by Patterson in U.S. Pat. Nos. 3,861,709 and 3,710,511. Inaddition to these methods, Albertsen et al., U.S. Pat. No. 5,432,068,describe a system of nuclear male sterility which includes: identifyinga gene which is critical to male fertility; silencing this native genewhich is critical to male fertility; removing the native promoter fromthe essential male fertility gene and replacing it with an induciblepromoter; inserting this genetically engineered gene back into theplant; and thus creating a plant that is male sterile because theinducible promoter is not “on” resulting in the male fertility gene notbeing transcribed. Fertility is restored by inducing, or turning “on”,the promoter, which in turn allows the gene that confers male fertilityto be transcribed. Male sterile soybean lines and characterization arediscussed in Palmer (2000) Crop Sci 40:78-83, and Jin et al. (1997) SexPlant Reprod 10:13-21.

5. Polynucleotides that create a site for site specific DNA integration.This includes the introduction of at least one FRT site that may be usedin the FLP/FRT system and/or a Lox site that may be used in the Cre/Loxsystem. For example, see Lyznik et al., Site-Specific Recombination forGenetic Engineering in Plants, Plant Cell Rep (2003) 21:925-932 and WO99/25821, which are hereby incorporated by reference. Other systems thatmay be used include the Gin recombinase of phage Mu (Maeser et al.(1991) Mol Gen Genet 230:170-176); the Pin recombinase of E. coli(Enomoto et al.

Other genes and transcription factors that affect plant growth andagronomic traits such as yield, flowering, plant growth and/or plantstructure, can be introduced or introgressed into plants, see e.g., WO97/49811 (LHY), WO 98/56918 (ESD4), WO 97/10339 and U.S. Pat.

Development of Soybean Sublines

Sublines of XBP49006 may also be developed. Although XBP49006 containssubstantially fixed genetics and is phenotypically uniform with nooff-types expected, there still remains a small proportion ofsegregating loci either within individuals or within the population as awhole. Sublining provides the ability to select for these loci, whichhave no apparent morphological or phenotypic effect on the plantcharacteristics, but may have an affect on overall yield. For example,the methods described in U.S. Pat. No. 5,437,697 and US2005/0071901 maybe utilized by a breeder of ordinary skill in the art to identifygenetic loci that are associated with yield potential to further purifythe variety in order to increase its yield (both of which are hereinincorporated by reference). Based on these teachings, a breeder ofordinary skill in the art may fix agronomically important loci by makingthem homozygous in order to optimize the performance of the variety. Nocrosses to a different variety are made, and so a new genetic variety isnot created and the overall genetic composition of the variety remainsessentially the same. The development of soybean sublines and the use ofaccelerated yield technology is a plant breeding technique.

Soybean varieties such as XBP49006 are typically developed for use inseed and grain production. However, soybean varieties such as XBP49006also provide a source of breeding material that may be used to developnew soybean varieties. Plant breeding techniques known in the art andused in a soybean plant breeding program include, but are not limitedto, recurrent selection, mass selection, bulk selection, backcrossing,pedigree breeding, open pollination breeding, restriction fragmentlength polymorphism enhanced selection, genetic marker enhancedselection, making double haploids, and transformation. Oftencombinations of these techniques are used. The development of soybeanvarieties in a plant breeding program requires, in general, thedevelopment and evaluation of homozygous varieties. There are manyanalytical methods available to evaluate a new variety. The oldest andmost traditional method of analysis is the observation of phenotypictraits but genotypic analysis may also be used.

Methods for producing a soybean plant by crossing a first parent soybeanplant with a second parent soybean plant wherein the first and/or secondparent soybean plant is variety XBP49006 are provided. The other parentmay be any soybean plant, such as a soybean plant that is part of asynthetic or natural population. Any such methods using soybean varietyXBP49006 include but are not limited to: selfing, sibbing, backcrossing,mass selection, pedigree breeding, bulk selection, hybrid production,crossing to populations, and the like. These methods are well known inthe art and some of the more commonly used breeding methods aredescribed below. Descriptions of breeding methods can be found in one ofseveral reference books (e.g., Allard, Principles of Plant Breeding,1960; Simmonds, Principles of Crop Improvement, 1979; Sneep et al.,1979; Fehr, “Breeding Methods for Cultivar Development”, Chapter 7,Soybean Improvement, Production and Uses, 2^(nd) ed., Wilcox editor,1987).

Pedigree breeding starts with the crossing of two genotypes, such asXBP49006 and another soybean variety having one or more desirablecharacteristics that is lacking or which complements XBP49006. If thetwo original parents do not provide all the desired characteristics,other sources can be included in the breeding population. In thepedigree method, superior plants are selfed and selected in successivefilial generations. In the succeeding filial generations, theheterozygous allele condition gives way to the homozygous allelecondition as a result of inbreeding. Typically in the pedigree method ofbreeding, five or more successive filial generations of selfing andselection is practiced: F1→F2; F2→F3; F3→F4; F4→F5, etc. After asufficient amount of inbreeding, successive filial generations willserve to increase seed of the developed variety. Typically, thedeveloped variety comprises homozygous alleles at about 95% or more ofits loci.

In addition to being used to create backcross conversion populations,backcrossing can also be used in combination with pedigree breeding. Asdiscussed previously, backcrossing can be used to transfer one or morespecifically desirable traits from one variety (the donor parent) to adeveloped variety (the recurrent parent), which has overall goodagronomic characteristics yet lacks that desirable trait or traits.However, the same procedure can be used to move the progeny toward thegenotype of the recurrent parent but at the same time retain manycomponents of the non-recurrent parent by stopping the backcrossing atan early stage and proceeding with selfing and selection. For example, asoybean variety may be crossed with another variety to produce a firstgeneration progeny plant. The first generation progeny plant may then bebackcrossed to one of its parent varieties to create a BC1F1. Progenyare selfed and selected so that the newly developed variety has many ofthe attributes of the recurrent parent and yet several of the desiredattributes of the donor parent. This approach leverages the value andstrengths of the recurrent parent for use in new soybean varieties.

Therefore, in some examples a method of making a backcross conversion ofsoybean variety XBP49006, comprising the steps of crossing a plant ofsoybean variety XBP49006 with a donor plant possessing a desired trait,selecting an F1 progeny plant containing the desired trait, andbackcrossing the selected F1 progeny plant to a plant of soybean varietyXBP49006 are provided. This method may further comprise the step ofobtaining a molecular marker profile of soybean variety XBP49006 andusing the molecular marker profile to select for a progeny plant withthe desired trait and the molecular marker profile of XBP49006. In oneexample the desired trait is a mutant gene or transgene present in thedonor parent.

Recurrent selection is a method used in a plant breeding program toimprove a population of plants. XBP49006 is suitable for use in arecurrent selection program. The method entails individual plants crosspollinating with each other to form progeny. The progeny are grown andthe superior progeny selected by any number of selection methods, whichinclude individual plant, half-sib progeny, full-sib progeny and selfedprogeny. The selected progeny are cross pollinated with each other toform progeny for another population. This population is planted andagain superior plants are selected to cross pollinate with each other.Recurrent selection is a cyclical process and therefore can be repeatedas many times as desired. The objective of recurrent selection is toimprove the traits of a population. The improved population can then beused as a source of breeding material to obtain new varieties forcommercial or breeding use, including the production of a syntheticcultivar. A synthetic cultivar is the resultant progeny formed by theintercrossing of several selected varieties.

Mass selection is a useful technique when used in conjunction withmolecular marker enhanced selection. In mass selection seeds fromindividuals are selected based on phenotype or genotype. These selectedseeds are then bulked and used to grow the next generation. Bulkselection requires growing a population of plants in a bulk plot,allowing the plants to self-pollinate, harvesting the seed in bulk andthen using a sample of the seed harvested in bulk to plant the nextgeneration. Also, instead of self pollination, directed pollinationcould be used as part of the breeding program.

Mutation breeding is another method of introducing new traits intosoybean variety XBP49006. Mutations that occur spontaneously or areartificially induced can be useful sources of variability for a plantbreeder. The goal of artificial mutagenesis is to increase the rate ofmutation for a desired characteristic. Mutation rates can be increasedby many different means including temperature, long-term seed storage,tissue culture conditions, radiation; such as X-rays, Gamma rays (e.g.,cobalt 60 or cesium 137), neutrons, (product of nuclear fission byuranium 235 in an atomic reactor), beta radiation (emitted fromradioisotopes such as phosphorus 32 or carbon 14), ultraviolet radiation(preferably from 2500 to 2900 nm), or chemical mutagens such as baseanalogues (5-bromo-uracil), related compounds (8-ethoxy caffeine),antibiotics (streptonigrin), alkylating agents (sulfur mustards,nitrogen mustards, epoxides, ethylenamines, sulfates, sulfonates,sulfones, lactones), azide, hydroxylamine, nitrous acid, or acridines.Once a desired trait is observed through mutagenesis, the trait may thenbe incorporated into existing germplasm by traditional breedingtechniques. Details of mutation breeding can be found in “Principles ofCultivar Development” Fehr, 1993 Macmillan Publishing Company. Inaddition, mutations created in other soybean plants may be used toproduce a backcross conversion of XBP49006 that comprises such mutation.

Molecular markers, which includes markers identified through the use oftechniques such as isozyme electrophoresis, restriction fragment lengthpolymorphisms (RFLPs), randomly amplified polymorphic DNAs (RAPDs),arbitrarily primed polymerase chain reaction (AP-PCR), DNA amplificationfingerprinting (DAF), sequence characterized amplified regions (SCARs),amplified fragment length polymorphisms (AFLPs), simple sequence repeats(SSRs) and single nucleotide polymorphisms (SNPs), may be used in plantbreeding methods utilizing XBP49006.

Isozyme electrophoresis and RFLPs have been widely used to determinegenetic composition. Shoemaker and Olsen, ((1993) Molecular Linkage Mapof Soybean (Glycine max L. Merr.). p. 6.131-6.138. In S. J. O'Brien(ed.) Genetic Maps: Locus Maps of Complex Genomes. Cold Spring HarborLaboratory Press. Cold Spring Harbor, N.Y.), developed a moleculargenetic linkage map that consisted of 25 linkage groups with about 365RFLP, 11 RAPD (random amplified polymorphic DNA), three classicalmarkers, and four isozyme loci. See also, Shoemaker R. C. 1994 RFLP Mapof Soybean. P. 299-309 In R. L. Phillips and I. K. Vasil (ed.) DNA-basedmarkers in plants. Kluwer Academic Press Dordrecht, the Netherlands.

SSR technology is an efficient and practical marker technology; moremarker loci can be routinely used and more alleles per marker locus canbe found using SSRs in comparison to RFLPs. For example Diwan andCregan, described a highly polymorphic microsatellite loci in soybeanwith as many as 26 alleles. (Diwan, N., and P. B. Cregan 1997 Automatedsizing of fluorescent-labeled simple sequence repeat (SSR) markers toassay genetic variation in Soybean Theor. Appl. Genet. 95:220-225).Single nucleotide polymorphisms (SNPs) may also be used to identify theunique genetic composition of the XBP49006 and progeny varietiesretaining or derived from that unique genetic composition. Variousmolecular marker techniques may be used in combination to enhanceoverall resolution.

Soybean DNA molecular marker linkage maps have been rapidly constructedand widely implemented in genetic studies. One such study is describedin Cregan et. al, “An Integrated Genetic Linkage Map of the SoybeanGenome” Crop Science 39:1464-1490 (1999). Sequences and PCR conditionsof SSR Loci in Soybean as well as the most current genetic map may befound in Soybase on the world wide web.

One use of molecular markers is quantitative trait loci (QTL) mapping.QTL mapping is the use of markers, which are known to be closely linkedto alleles that have measurable effects on a quantitative trait.Selection in the breeding process is based upon the accumulation ofmarkers linked to the positive effecting alleles and/or the eliminationof the markers linked to the negative effecting alleles from the plantgenome.

Molecular markers can also be used during the breeding process for theselection of qualitative traits. For example, markers closely linked toalleles or markers containing sequences within the actual alleles ofinterest can be used to select plants that contain the alleles ofinterest during a backcrossing breeding program. The markers can also beused to select for the genome of the recurrent parent and against thegenome of the donor parent. Using this procedure can minimize the amountof genome from the donor parent that remains in the selected plants. Itcan also be used to reduce the number of crosses back to the recurrentparent needed in a backcrossing program. The use of molecular markers inthe selection process is often called genetic marker enhanced selection.

Production of Double Haploids

The production of double haploids can also be used for the developmentof plants with a homozygous phenotype in the breeding program. Forexample, a soybean plant for which XBP49006 is a parent can be used toproduce double haploid plants. Double haploids are produced by thedoubling of a set of chromosomes (1N) from a heterozygous plant toproduce a completely homozygous individual. For example, see Wan et al.,“Efficient Production of Doubled Haploid Plants Through ColchicineTreatment of Anther-Derived Maize Callus”, Theoretical and AppliedGenetics, 77:889-892, 1989 and US2003/0005479. This can be advantageousbecause the process omits the generations of selfing needed to obtain ahomozygous plant from a heterozygous source.

Methods for obtaining haploid plants are disclosed in Kobayashi, M. etal., J Heredity 71:9-14, 1980, Pollacsek, M., Agronomie (Paris)12:247-251, 1992; Cho-Un-Haing et al., J Plant Biol., 1996, 39:185-188;Verdoodt, L., et al., 1998, 96:294-300; Genetic Manipulation in PlantBreeding, Proceedings International Symposium Organized by EUCARPIA,Sep. 8-13, 1985, Berlin, Germany; Chalyk et al., 1994, Maize Genet Coop.Newsletter 68:47. Double haploid technology in soybean is discussed inCroser et al. (2006) Crit Rev Plant Sci 25:139-157; and Rodrigues et al.(2006) Brazilian Arc Biol Tech 49:537-545.

In some examples a process for making a substantially homozygousXBP49006 progeny plant by producing or obtaining a seed from the crossof XBP49006 and another soybean plant and applying double haploidmethods to the F1 seed or F1 plant or to any successive filialgeneration is provided. Based on studies in maize and currently beingconducted in soybean, such methods would decrease the number ofgenerations required to produce a variety with similar genetics orcharacteristics to XBP49006. See Bernardo, R. and Kahler, A. L., Theor.Appl. Genet. 102:986-992, 2001.

In particular, a process of making seed retaining the molecular markerprofile of soybean variety XBP49006 is contemplated, such processcomprising obtaining or producing F1 seed for which soybean varietyXBP49006 is a parent, inducing doubled haploids to create progenywithout the occurrence of meiotic segregation, obtaining the molecularmarker profile of soybean variety XBP49006, and selecting progeny thatretain the molecular marker profile of XBP49006.

Methods using seeds, plants, cells, or plant parts of variety XBP49006in tissue culture are provided, as are the cultures, plants, parts,cells, and/or seeds derived therefrom. Tissue culture of various tissuesof soybeans and regeneration of plants therefrom is well known andwidely published. For example, see Komatsuda, T. et al., “Genotype XSucrose Interactions for Somatic Embryogenesis in Soybean,” Crop Sci.31:333-337 (1991); Stephens, P. A. et al., “Agronomic Evaluation ofTissue-Culture-Derived Soybean Plants,” Theor. Appl. Genet. (1991)82:633-635; Komatsuda, T. et al., “Maturation and Germination of SomaticEmbryos as Affected by Sucrose and Plant Growth Regulators in SoybeansGlycine gracilis Skvortz and Glycine max (L.) Merr.,” Plant Cell, Tissueand Organ Culture, 28:103-113 (1992); Dhir, S. et al., “Regeneration ofFertile Plants from Protoplasts of Soybean (Glycine max L. Merr.):Genotypic Differences in Culture Response,” Plant Cell Reports (1992)11:285-289; Pandey, P. et al., “Plant Regeneration from Leaf andHypocotyl Explants of Glycine wightii (W. and A.) VERDC. var.longicauda,” Japan J. Breed. 42:1-5 (1992); and Shetty, K., et al.,“Stimulation of In Vitro Shoot Organogenesis in Glycine max (Merrill.)by Allantoin and Amides,” Plant Science 81:(1992) 245-251; as well asU.S. Pat. No. 5,024,944, issued Jun. 18, 1991 to Collins et al. and U.S.Pat. No. 5,008,200, issued Apr. 16, 1991 to Ranch et al., thedisclosures of which are hereby incorporated herein in their entirety byreference. Thus, another aspect is to provide cells which upon growthand differentiation produce soybean plants having the physiological andmorphological characteristics of soybean variety XBP49006.
